Application filed March 22, 1909. Serial No. 485,040.

To all '11:): om it may con cern Be it known that I. Tiinooonc A. DIsssL, of Boston. in the count of Suffolk and State of Massachusetts. have. invented an Improvement in CableSuppm-ts. of which fication, like letters the drawings representing like parts.

'Ehe present invention relates to a s12pporting clip ofthe kind now commonly used in supporting telephone cables and wires, or tlie like-,where a span wire extends from pole to pole, while the cable is hung in loops or ring-shaped clips secured on the span wir.

it is the purpose of the present invention to obtain a cable or wire supporting device which will hold itself firmly in position upon the span wire, and at the same time be easily attachable thereto without- .the use of pliers or similar tools. For this purpose. the support or clip embodying the invention is fiormed of a single piece of resilient material eat to form a loop or ring of sufficient size to hoid the goblet)!" wires, the opp site ends of the piece of material passing each other above the loop, and being bent or twisted in opposite directions to- :lt'orm helical extensions or pig-tails of such mane as to extend around and contor'm i the resiiiency of the natsriai oi clip is made. The lifi extensions pop areseparatcd afthe top where each other, so that turning the R angle to the span w1re the ends or ensions can he passed above the .u wire crossing the in opposite s when. the clip has been. turned to tion. and then being snapped the span wire extending in helix over and under the lame *tions, for some distance at loop. 1 a le elevation of a span Wire clip ei'ahodying the invcnits operative posiowing, in dotted lines 1 the ciip turned e wan Wire; Fig. 2 is a g a cross sec-- with the clip thereon; we similar to Fig. 3,

dying; the ire upon the span Wire the. following, descriptuin. in connection with the accompanying drawings, is a f-[)GC1-' s span wire and to be frictionally held.

vention consists of a piece of material, such as galvanized wire, having sufficient strength to support a cable or wires, and sufiicient resiliency to besprung into place and to frictionally hold itself thereon, the clip being shaped to form the main supporting loop (1, the ends of which are carried upward and pa s each other. 1 The said ends are then bent or twisted to form the helical extensions or pig-tails and a", thehelices being in opposite direc tious to each other. Where the extensions of the loop pass eaclrotlier, they are laterally separated, as indicated in Figs. 1 and 2, thereby affording a space between the p0rtions (6 and a (Fig. 2) so that by turning the clip to the dotted line position shown in Figs. 1 and 2, the ends arid (1- can be brought above the span wire Z) and caused to cross the said span wirein opposite'directions when the clip is turned to its full line position. The helical pig tails a and a can then be sprung around the span Wire and snapped into place, thereby causing the clip to have a firm frictional hold upon the span wire 71. By making theextcnsiens a and a of sufficient length, a firm frictional bold is obtained upon the span wire, it being easy. however, to snap the ends into. position around the said wire. The separation of the parts a and a also admits of the passing of the two helical extensions over the span wire in opposite directions, instead of both eing passed over the said wire from the some side, as in the devices of a similar nature which have heretofore been constructed. This feature 'of the device is particularly valuable in replacing supports on existing lines, as it permits the device to be readily attached over cables or wires-already in position below a span Wire.

The helical extensions, as shown, may be arranged so as to extend substantially ones around the strand, being elongated to an extent suilicient to admit of being easily si'ia'ppcd into place.

in order to obiain a relatively large bearing surface for the cable or wires supported in the loop, without. unnecessarily increasing tion of the material which forms the lower part of the loop may be flattened in, crosssection, shown in Fig. 4-.

It is also practicable to make clip of wire flattened in cross-section, as sho n in Fig. 5, the wire in this case being the amount of material. v that porthe entire twisted so that the shorter diameter is transportion can be readily snapped into place around the span-wire.

Claims- 1. A supporting clip consisting of a sin le iece of resilient material in the form 0 a cop, the ends'of which loop pass each other with space for a supportingiwlre to lie therebetween, said ends being extended into helices at opposite sides of the loop whereby said helices and said loop form a continuous helix having therein asingle enlarged convolution.

2. A supporting clip which consists of a wire in the form of a continuous coil adapted to be sprung around a supporting wire and having a coil ofi relatively large diameter arranged centrally thereof and adapted to support a cable.

3. A supporting-clip consisting of, a single piece of resilient material curved in the form of a loop, the ends of the material passing each other and the curve being continued to form an elongated-helix of smaller diameter,

adapted to engage a span-wire.

4. A supportln t cli having a supportin loop for e-able and resi ient members adapte to be sprung upon and to conform to a span wire, said members extending laterally fromthe upper portion of said loop upon opposite sides thereof and formed to meet said loop from opposite sides of said span wire.

5. A supporting eli consisting of a piece of resilient material bent in the form of a continuouscoil of substantially three turns, the outside turns of which are smaller and more elongated than the inside turn.

, 6. A-supporting clip consisting of a single piece of resilient material having a portion thereof flattened and curved to form a loop, the plane of said loop being at right angles to the axis of the span wire, the ends of the i i l I material passing each other'fand the curve being continued in said ends to form an elongated helix, of smaller diameter adapted to en agea s an wire.

7 in com ination with a supportin strand, an aerial-cable support consisting o a piece of resilient wire bent to form a loop, the ends of said wire extending upwardly above said loop and adapted to pass upon v opposite sides of said strand, one of said ends then being bent forwardly and downwardly, and the other thereof being bent rearwardly and downwardly, both of said strands being finally bent upwardly whereby each end forms an extended. loop adapted to grasp said strand and to exert pressure upon opposite sides thereof.

8. In combination with a supporting strand, an aerial-cable support consisting of a piece of wire bent to form a loop at rlght angles to the axis of the supporting strand, the ends of said wire extending upwardly upon opposite sides of said strand, then bent outwardly at an angle to said loop in opposite directions and formed to hold said strand with a spring grip.

9. A supfporting clip consistin of a single piece 0 resilient material in t e form of a loop disposed at right angles to the axis of a supporting wire, the ends of which loop extend upwardly with space adapted to receive the supporting wire therebetween, said ends being then bent downwardly and outwardly to form retaining members adapted to be sprung u on said supporting wire from opposite si es thereof.

-In testlmony whereof, I have signed my 0 name to this specification in the presence of two subscribing Witnesses.
